Question

What is the maximum number of ATP molecules that could be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to $C{O}_2$ and $H_{2}O$ yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 Kcal?

• A. 57
• B. 1
• C. 2
• D. 30

Answer 1

The correct option is A 57

If one mole of ATP is equal to 12 Kcal, then total 686 Kcal of energy will produce total of 57 ATP molecules which can be calculated by dividing 686 by 12.
